Application of Back-side Laser Technique on Failure Analysis

Abstract

The application of backside emission and laser technique (TIVA/OBIRCH) had been widely used in the semiconductor industry. This paper will discuss the usage of backside laser damage method to aid in this technique on localizing the failure spot. Two applications on backside laser; 1.Memory scramble verification and 2. Yield loss scenario using backside laser to verify the failure hypothesis will also be discussed.
